Abstract
A display and finger print reader assembly for an electronic device includes a display having an arrangement of light emitting pixels, a light guide juxtaposed the arrangement of pixels of the display, and light sensors disposed at different locations around a periphery of the light guide. Light is sequentially emitted from the pixels to illuminate a user's finger that is placed against the display and finger print reader assembly. The emitted light that is reflected by the user's finger propagates in the light guide to one or more of the light sensors and indicates a fingerprint characteristic of a portion of the user's finger adjacent the pixel or pixels from which the light is emitted.
